Great, I have seen that you improved it a lot! Thanks.
I have two another improvements (and changed the script at
http://user.mendelu.cz/marik/sage/sage2tex )
First:
The following lines can be used to process tables created by
html.table command, see the file http://user.mendelu.cz/marik/sage/integral.pdf
obsah=string.replace(obsah,"<table class=\"table_form\">","{\
\offinterlineskip\\halign{\\vrule \\vrule width 0 pt height 14pt depth
5pt # &&\\vrule # \\cr\\noalign{\\hrule}")
obsah=string.replace(obsah,"<tbody>","%")
obsah=string.replace(obsah,"</tbody>","%")
obsah=string.replace(obsah,"</table>","\\noalign{\\hrule}}}")
obsah=string.replace(obsah,"<tr>","\\global\\def\\optcr{\\vskip 2
pt\\hrule}")
obsah=string.replace(obsah,"<tr class =\"row-a\">","\\global\\let\
\optcr\\relax{}")
obsah=string.replace(obsah,"<tr class =\"row-b\">","\\global\\let\
\optcr\\relax{}")
obsah=string.replace(obsah,"</tr>","\\cr\\noalign{\\hrule\
\optcr}")
obsah=string.replace(obsah,"<th>","\\quad\\textbf{")
obsah=string.replace(obsah,"</th>","} & ")
obsah=string.replace(obsah,"<td>","\\quad ")
obsah=string.replace(obsah,"</td>"," & ")
Second: TeX does not understand \textcolor[HTML]{ff0000}{stuff}. So
these lines convert into \textcolor[HTML]{FF0000}{stuff} (replacement
for previous version of this regexp substitution)
regular=re.compile(r"<span style=\"color: #(.*?);\">")
obsah=regular.sub(lambda x: "\\textcolor[HTML]{"+x.group(1).upper()
+"}{",obsah)

I am O.K. with any free licence, GNU GPL, Creative Commons or any
other.
In fact, the script was so simple that I was not thinking about any
licence.
I have no skills in programing in Python or any other object oriented
langugae and you cannot expect, that I can help to improve it into a
form which could be used for sufficiently big set of sage worksheets,
including complicated html, 3D graphics, included external pictures
and some other things.
Would you like to work a bit deeper on conversion between Sage and
TeX? If yes, then everything is up to you and from my point of view it
is sufficient to state somewhere, that the initial version was based
on the work of Robert Marik.
Thank you very much
Robert
